Question

I have this function;

static public void Print(Object[] arr) {
    for(int i = 0; i < arr.length; i++)
        System.out.println(i + " => " + arr[i]);
}

I want to use that for every primitive type array. Isn’t there any way to do that without overriding it for every primitive type?

Note: This is just an example function. I want to know the technique if there is one.

Answer 1

No, this is not possible. Array element types are not wrapped, Object[] formal parameter is not applicable for e.g. int[] actual parameter. You have to write one method per primitive type, as in java.util.Arrays. Ugly, but the only way.
